Charging antimony-free VRLA batteries without float
Here is a proposed much lower float current method to charge non-antimony batteries. Supposedly better than traditional float. Low current float for AGM
Forum Discussion
I am looking not to cook my AGMs. For a while I was thinking 24x7 float was the best thing for them while in storage. I am rethinking that. Maybe what the PWM does is fine.
Float is a very specific temp corrected voltage that leads to a certain current level. This is a charge rate below that. I guess below float might be more accurate.
I devised a way to watch for outgassing on my AGMs and they will evolve hydrogen and oxygen much more easily than many people think. A little does not hurt, but much dries out the battery...forever reducing capacity. I am looking for that tightrope between sulfation and outgassing.
